Douglas Elliman broker Paul Hansen, a 53-year-old dad of two, was killed after real estate developer Ludwick crashed his car into a pole outside Hansen’s Sag Harbor home last August. Ludwick left Hansen, who was a passenger in his car, to die on the side of the road as he fled the scene.

Hansen’s widow, Catherine, has filed a wrongful death claim in Suffolk County against Ludwick, seeking up to $10 million from the BlackHouse Development owner. The sides are back in court on Feb. 10, when Hansen family lawyers will ask the judge to prevent Ludwick, who’s now jailed in Riverhead, LI, from transferring any of his assets offshore or into someone else’s name. He’s believed to be worth $20 million.

The move comes after the developer — who also faces criminal vehicular manslaughter charges that carry more than 30 years in prison — was nabbed in January after flying to Puerto Rico, taking sailing lessons and transferring nearly $400,000 into an account to buy a boat to flee to South America.

He’d also typed in more than 1,000 suspicious Web searches, including for “five countries with no extradition treaties,” “seeking citizenship in Venezuela” and “would you survive as a fugitive.”

Hansen family lawyer Scott Middleton said, “Given the behavior of Sean Ludwick, from the very beginning, at the accident scene, to his most recent escapade in trying to jump bail by purchasing a boat and sailing off to Venezuela, I have serious misgivings about his taking responsibility for his actions.”

He added that he hoped the judge would rule that Ludwick would “not be able to secrete or otherwise dispose of his assets without court approval. This will enable us to litigate the case and be confident that he will be able to satisfy what we expect to be a large judgment against him for taking the life of Paul Hansen.”
